My Domino server actually accept emails for recipients address which do not exist and send them to recipients who have a name very similar.
For example, if I receive email for firstname.lastname@example.org and this email does not exist, he would send it to email@example.com (which exist and looks a bit similar)
Same for my own address firstname.lastname@example.org. If I receive an email for email@example.com without the dot, I would receive it anyway.
I need to disable this
How should I do?
